WASHINGTON – A man was struck and killed by a car Thursday morning while walking along a sidewalk in Fort Washington, police say.

Prince George’s County police officials say the crash happened just before 6:30 a.m. in the 9200 block of Livingston Road. At the time of the incident, police say that a driver fell asleep at the wheel and struck a curb near where a man was walking.

The driver woke up when the car hit the curb, police say, but he was unable to regain control of the vehicle before hitting the victim.

Police say speed, alcohol and drugs are not thought to be factors in the incident, which remains under investigation.
